Harvia Forte is a heat-storing electric sauna heater with a thermally insulated housing and a closed stone compartment. The heater features a standby mode that keeps the sauna stones hot and allows the sauna to be quickly prepared for use.
The heat-storing design and large stone capacity provide soft and even steam at various sauna temperatures. Water is poured onto the heated stones only after opening the heater lid.
HARVIA Forte is best suited for well-insulated saunas without large heat-absorbing surfaces such as concrete, natural stone, glass blocks, or massive log structures.
The separate digital control panel can be installed either inside or outside the sauna room. The heater is also suitable for integration into sauna bench structures using manufacturer-approved installation solutions.
The stone standby temperature can be adjusted between 220 °C and 280 °C, while during active heating the stone temperature may exceed 300 °C. The manufacturer recommends using sauna stones larger than 10 cm to ensure sufficient airflow gaps between the stones and proper air circulation within the stone compartment.
Sauna stones are sold separately.
